SFH601-5X

Overview

The SFH601-5X is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features an infrared LED input and an NPN silicon phototransistor output with a base terminal, housed in a 6-DIP package. The device provides high isolation voltage of 5300Vrms. Key electrical parameters include a maximum DC forward current (If) of 60 mA, collector-emitter breakdown voltage (BVCEO) of 60 V, and a typical collector-emitter saturation voltage (Vce(sat)) of 400 mV. The unit operates within a temperature range of -55°C to +100°C.

Feature Summary

• Integrates an infrared emitting diode with an NPN silicon phototransistor for signal transmission.
• Includes a dedicated base terminal on the phototransistor to facilitate faster switching speeds and improved linearity.
• Provides robust electrical isolation between input and output circuits via a 5300Vrms dielectric barrier.

Applications

• Logic-to-logic isolation in noisy industrial environments
• Line receiver circuits
• Programmable current level sensing

Procurement Notes

Verify the specific suffix '5X' against official Isocom documentation to confirm exact binning or packaging specifications. Ensure compatibility with existing PCB footprints for 6-DIP packages. Cross-reference replacement part numbers such as SFH601-2 if availability is constrained. Confirm RoHS compliance status for the specific manufacturing batch prior to integration into final assemblies.

Selection Notes

Select this component when high-speed switching is required due to the presence of the phototransistor base terminal. It is suitable for applications demanding high isolation voltage up to 5300Vrms. Consider the 60 mA forward current limit and 60 V collector-emitter breakdown voltage when designing drive and load circuits. Ensure the operating temperature range meets the environmental requirements of the target application.
